- 3. A yarn steaming machine according to claim 2, wherein the maximum rotational angle range of the winding head is 45.degree..
- 4. A yarn steaming machine according to claim 1, wherein the winding head is inhibited from rotating with the winding flyer by means of a magnetic field.
- 5. A yarn steaming machine according to claim 4, wherein the winding head is inhibited from rotating with the winding flyer through a magnetostatic attraction between a magnet and a body which is attracted by the latter, one of the magnet and body being disposed in a non-rotatable manner on the machine frame and the other being disposed on the winding body.
- 6. A yarn steaming machine according to claim 5, wherein the body which is attracted by the magnet is also a magnet.
- 7. A yarn steaming machine according to claim 5, wherein the magnet is a permanent magnet.
- 8. A yarn steaming machine according to claim 4, wherein the magnetic field passes through a winding surface of the winding head.
- 9. A yarn steaming machine according to claim 1, wherein a winding surface of the winding head has a greater diameter in a loop winding region than in a loop deposit region.
- 10. A yarn steaming machine according to claim 9, wherein the diameter of the winding surface decreases from the loop winding region in the direction of the loop deposit region as the distance from the loop winding region increases.
- 11. A yarn steaming machine according to claim 1, wherein the winding head is formed so as to deposit the yarn loops directly as a yarn loop layer on the conveyor device.
- 12. A yarn steaming machine according to claim 11, wherein the winding head deposits the yarn loops directly on a conveyor belt of the conveyor device.
- 13. A yarn steaming machine according to claim 1, wherein the winding head is disposed with an end face facing the conveyor device.
- 14. A yarn steaming machine according to claim 11, wherein the winding flyer guides the yarn between guide eyes in a free-running manner.
- 15. A yarn steaming machine according to claim 11, wherein the winding flyer comprises a yarn outlet which is elongate in the azimuthal direction for the delivered yarn.
- 16. A yarn steaming machine comprising:
- a steaming device,
- a conveyor device for conveying yarn laid in the form of a yarn loop layer through the steaming device,
- a loop forming device, which forms the yarn loop layer, and
- a draw-off device, which breaks up the yarn loop layer following its passage through the steaming device by drawing off the yarn, wherein:
- a turning device is disposed before the draw-off device to make an underside of the yarn loop layer lying on the conveyor device accessible for drawing off the yarn; and
- the yarn loop layer can be removed from the conveyor device by a gas stream which acts on the layer.
- 17. A yarn steaming machine according to claim 16, wherein the turning device comprises a turning wheel which takes up the yarn loop layer, and the yarn loop layer can be fixed at a contact surface of the turning wheel by the gas stream.
- 18. A yarn steaming machine according to claim 17, wherein the gas stream fixes the yarn loop layer in a first contact segment of the turning wheel at the contact surface thereof.
- 19. A yarn steaming machine according to claim 17, wherein the contact surface of the turning wheel comprises passages through which the gas stream passes.
- 20. A yarn steaming machine according to claim 19, wherein the turning wheel comprises web elements forming the contact surface and the passages.
- 21. A yarn steaming machine according to claim 20, wherein the web elements have edges which are rounded towards the passages.
- 22. A yarn steaming machine according to claim 16, wherein the loop forming device comprises a winding flyer which guides the yarn between guide eyes in a free-running manner.
- 23. A yarn steaming machine according to claim 22, wherein the yarn is guided in the winding flyer through a central deflector eye and an end guide eye disposed at the yarn outlet.
- 24. A yarn steaming machine according to claim 22, wherein the winding flyer comprises a yarn outlet which is elongate in the azimuthal direction for the delivered yarn.
- 25. A yarn steaming machine according to claim 24, wherein the winding flyer comprises a guide duct which is elongate in the azimuthal direction for the delivered yarn.
- 26. A yarn steaming machine according to claim 24, wherein the yarn outlet, viewed in the azimuthal direction, comprises at the end a U-shaped guide eye for the yarn.
- 27. A yarn steaming machine according to claim 26, wherein the yarn outlet comprises a U-shaped guide eye for the yarn at both ends.
- 28. A yarn steaming machine comprising:
- a steaming device,
- a conveyor device for conveying yarn laid in the form of a yarn loop layer through the steaming device,
- a loop forming device, which forms the yarn loop layer, and
- a draw-off device, which breaks up the yarn loop layer following its passage through the steaming device by drawing off the yarn, wherein:
- a turning device is disposed before the draw-off device to make an underside of the yarn loop layer lying on the conveyor device accessible for drawing off the yarn; and
- said loop forming device comprises a winding flyer which guides the yarn between guide eyes in a free-running manner.
- 29. A yarn steaming machine according to claim 28, wherein the winding flyer comprises a plurality of yarn outlets for the delivered yarn.
- 30. A yarn steaming machine according to claim 28, wherein the winding flyer is formed by a flyer bell whose bottom closure carries the yarn outlet.
- 31. A yarn steaming machine according to claim 30, wherein the flyer bell is provided with an inner body which rises above the bottom closure and which forms the guide duct between itself and the flyer bell.
